FORK SCRAPER.

Specification of Letters Patent.

Patented April 1'7, 1906.

Application filed August 30, 1905. Serial No. 276,444.

To all whom it may concern:

Be it known that we, ALEXANDER KoRMIL and FREDRIOK RADLOFF, citizens ofthe United States, residing at Goldendale, in the county of Klickitatand State of Washington, have invented certain new and usefulImprovements in Fork Scrapers, of which the following is aspecification.

This invention relates to a manure-fork, scraper, or like implementwhich may be used either in the field or on the road for collectingmaterial or matter and conveying the same to a suitable place ofdeposit, said im plement being of the type comprising tines, teeth, orthe like and of scoop form and having a solid back and an operating bailor handle for convenience of manipulation in giving proper direction tothe scraper in its progress and dumping.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand'accompanying drawings.

WVhile the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essential features thereof, still the preferred embodiment isshown in the accompanying drawings, in which Figure 1 is a perspectiveview of a fork scraper embodying the invention. Fig. 2 is a verticallongitudinal section thereof, showing the parts on a larger scale. Fig.3 is a plan view of the implement, parts being broken away. Fig. 4 is adetail perspective view of an end portion of the bottom reinforcement.Fig. 5 is a detail perspective view of an end portion of the back.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The scraper in its general appearance is of scoop form and is providedwith an upwardly and rearwardly extended bail 1 for convenience ofmanipulation and with forwardly-extended arms 2 for attachment of thedraft or operating tackle. The rear or bowl portion of the scraper issolid and is composed of a number of plates riveted or otherwisefastened, and the forward portion is composed of a series of tines orteeth which will more readily penetrate fertilizer or loose material,such as rock, manure, and compost. The horizontal or bottom tines orteeth are provided in two series 3 and 4, the latter being stouter andlonger than the tines 3 and spaced a greater distance apart. The tinesor teeth 3 are provided in groups, preferably two to each group, whichare arranged between the tines 4. The tines or teeth 4 are madesufliciently stout and heavy to carry the load, Whereas the tines 3serve chiefly to fill the space between the tines 4 and prevent droppingor escape of the material when received upon the fork. The tines 3 maybe designated as fillers, and the tines 4 as load-carriers. The tines ofthe different sets are regularly spaced, as shown most clearly in Fig.3. The rear portion of each tine is bent approximately at a right angle,as shown at 5, and extends upward in the rear of the back 6 and isfastened thereto. The bent portion 5 is apertured to receive thefastenings 7 and 8, which may be bolts or rivets. Tines 9, located atthe sides of the scraper, decrease in length from the bottom upward andare of lance form, so as to offer a minimum amount of resistance whenthe lscrajlper is forced into material to receive a The back portion ofthe scraper comprises an upright wall 6, endwalls 10, and a bottom 11,said parts being preferably of integral formation to obviate theformation of joints and insure the provision of a substantial structure.A series of openings 12 are formed along the lower edge of the back orupright walls 6 adjacent to the bottom 11 and receive the tines or teethwhich pass therethrough, thereby enabling said tines to rest upon thebottom 11 and to have their bent ends 5 extend in the rear of the back6. Fastenings 13 connect the rear portions of the tines with the forwardportion of the bottom 11. A back plate 14 covers the bent ends 5 of thetines, and its upper edge is offset, as shown at 15, extending over theupper extremities of the parts 5 and coming close a ainst the upper edgeof the back 6, to whic it is riveted or otherwise fastened. The backplate 14 serves to stren then the rear portion of the scraper, as welIas to cover the parts 5 and present a practical unbroken surface toprevent lodgment and accumulation of material upon the bent ends 5.secured to the upright wall 6 of the back by the same fastenings 7 and 8employed for fastening the parts 5 and 6. The bottom reinforcementconsists of a plate 16, a rear flange 17, end flanges 18, and angleextension 19. The plate 16 rests upon the rear portion of the tines withthe rear flange 17 close against the back 6 and the end flanges 18 snugagainst the ends 10, openings being pro vided in the flanges 17 and 18to receive the fastenings used for connecting the component partscomprising the rear portion of the strip. The angle extensions 19 comebetween the tines 3 and 4 and are riveted or otherwise fastened to thefront edge of the bottom 11, as indicated most clearly by the dottedlines in Fig. 2. The parts 19 brace the tines laterally and at the sametime close the space formed between the bottom plates 16 and 11 toexclude foreign matter, which would wedge therein and foul theimplement, as well as add to its weight and retain moisture, which wouldtend to cause the parts to corrode.

Plates 20 are secured to the ends 10 of the back and are formed upontheir inner faces with depressions to receive the rear ends of the tines9 and the lower ends of the side bars of the bail 1. The arms 2 areextensions of the plates 20. The plates 20, while reinforcing the ends10, serve to brace and fix the position of the tines 9 by reason of thedepressions which form seats, in which the end portions of said tines 9and side bars of the bail 1 enter.

The bail 1 is approximately of U form, and the lower ends of the sidebars are secured to the rear portion or back of the scraper in anysubstantial manner and are strengthened by means of braces 21, whichhave their upper ends of substantially U form to receive the side barsof the bail 1 and their lower portions inwardly curved, as shown at 22,and secured to the rear portion or back of the scraper in anysubstantial manner. Runners 23 are secured to the lower portion of theback and receive the wear and enable the device to move easily upon thesurface over which it may be employed.
